Glioblastoma multiforme (GBM) is the most common malignant brain tumors in adults [1]}. [2]} analyzed array CGH data in GBM using glioma data from [3]} along with control samples. [4]} used the data from [2]}, and created aCGH data corresponding to a pseudo-chromosome so that the resulting genome sequence have shorter regions of high amplitude gains (copy number additions) as well as a broad region of low amplitude loss (copy number deletions). To be precise, the combined array consists of aCGH data from chromosome 7 in GBM29 and chromosome 13 in GBM31. The aCGH data is presented in Figure REF , and is available from the archived version of the cghFlasso package in R.
